Bernie, The best way to obtain the correct adjustment without a CO meter is to follow the directions in the Technical Information Manuel but just use an analog dwell meter instead of both tools as the procedure suggests. Unfortunately as David T. pointed out you probably have additional problems such as a malfunctioning Lambda circuit or (more likely) damaged fuel injection components from stale and/or contaminated fuel. The cause of your problem must be resolved before fine tuning your CO adjustment as that is the last step in properly setting up a PRV engine.

That is another clue to me. The other one is that the PO said the car runs rich. Does anyone have a starting point for me on the mixture, not the noise.
